SPARK-ARRESTR.

SPECIFICATION forming part of Letters Patent. No. 364,857, dated June 14, 1887.

Application filed February 29, IBY. Serial No. 229,073. (No model.)

To nl l whom it may corv cem:

Be itknown that I, WILLIAM THoMAs REED,

. of the city of Winnipeg, in the county of Sel- `ment on the device patented tome November 9, 1886, No. 352,353; and itpconsists, essen-v K tially, in forming a central air-tube in the exhaast-pipe communicating with the interior of the smoke-box at a point near the bottom of the smoke-box,and extending thence to the mouth ofthe exhaust-nozzle, corrugated def1ecting-plates being arranged in the smoke box and stack, substantially in the manner hereinafter more particularly explained.

Figure l is a perspective sectional view of a smoke box and stack with my device applied. Fig. 2 is a Vsectional side view of the exhaust-pipe. Fig. 3 is a sectionalk rear View of the exhaust pipe.

A represents the exhaust-pipe, communicating in the usual manner with the cylinders of the engine.`

a is a central tube extending from a point near the bottom of the smoke-box B to the mouth of the exhaust-nozzle b.v

In the drawings I show the lower mouth of the tube a facing the front of the smoke-box; b ut I do not confine myself to that exact position, as any point near the bottom of the smoke-box will answer my purpose.

C is a' petticoat extending over the lower mouth of the tube a. The bottom of this petticoat C is preferably covered with wire-netting h in order to prevent large cinders entering theccntral tube, a.

The smoke-stack D is of the ordinary class known as straight 7 smoke-stacks; but I corrugate its bonnet at d, as indicated, and suspend in its center al corrugated cone, E, sub stantially in t-he manner indicated.

Fis a corrugateddeilecting-plate situated in front of the tubes G, as shown.

H is a corrugated base-plate, and I is a eor 7 vequalizing or distributing the draft equally over the surface of the tubes; and as a consequence I am able to use a much larger nozzle b than would be possible were the draft to be produced onlyT at the top of the smoke-box.

Owing to the form of my exhaust-nozzle I), the steam discharged from it will ascend the smoke-stack in the form of a hollow column, the center of which will contain a core of the cinders which may be drawn into the central tube, a. These einders will strike the corrugated cone E, and, flying off at atangent from Y it, will come in contact with the corrngations d, and in this way will be effectually ground to a powder before they canl escape from the stack.

Owing to the arrangement of the corrugated pla'tes F, H, and I, the cnders entering the smoke-box B from the tubes G will be ground pretty nely before they can escape through c the netting J or through the central tube, a.

Consequently the corrugated cone E- and corrugations d will not have a great deal of work to accomplish.

v What I claim as my invention is- 1. An exhaust-pipe having a .central tube extending from a point near the bottom of the smoke-.box to a point at or near the mouth of the exhanst-nozzle, substantially as and for the purpose specified.

2. An exhaust-pipe having a central tube extending from a point near the bottom of the smoke-box to a point at or near the mouth of the exhaust-nozzle, in combination with a pet tcoat extending over the lower mouth of the said tube, substantially as and for the purpose specified.

3. An exhaust-pipe having a central tube extendingfrom a point near the bottom of the IOO smokebox to :t point ut or near the mouth of tom of the smoke-box B to u point at or 'near the exhaust-nozzle, in combination with a petthe top of the exhaust-nozzle I), substantially tiooat extending over the lower mouth of the as and for the purpose specified. 2o
